To all whom it may'oonoern:

Be it known that I, WILLIAM'H. DAY, a citizen of the United. States,residing in East Haven, county of New Haven, State of Connecticut, haveinvented certain new and use-- ful Improvements in Index 0r File Leaves,of which the following is" a full, clear, and exact description.

This invention relates to indexes, files or indicators of that type inwhich a holder or carrier is employed to receive and mount a relativelylong'strip of paper or the like containing reference materiahor ifdesired, a plurality of cards containing such material. The carrier orholder is usually provided with some sort of guides or retaining meansby whichthe reference bearing members are held in operative position,and these carriers may be either swingingly mounted upon a frame to bemanipulated after the manner of the leaves of a book, as shown in thepat ent to R. D. Hayes, No. 1,223,168, granted April 17 1917, or may bemade in the form of shallow drawers adapted to be inserted in a filingcabinet.

' It is necessary to move the cards or strips of paper containing thereference material about in the holder to some extent and such movementis, of course, necessary when they are inserted into and removed fromthe holder. It is, therefore, desirable to so make theoholders orcarriers that the strips of paper will slide freely within the guidesand so that there will be no tendency for these strips or cards to catchorstick. Heretofore, the guides for retaining the reference strips havebeen formed by connecting tothe carrier base separate strips which areprovided with fianges spaced from the'base to the car rier, in such amanner that the joints between these separate pieces and the carrierbaselie adjacent the edges of the reference strips. This often resultsin the edge of the strip entering into the crevice or crack of thisjoint between the'two members and becoming wedged therein so that freemove ment of the strip is prevented.

One object of my invention is to ove come the disadvantages abovereferred to and-to provide a carrier wi-th'suitable retaining guides soformed that the joint between these guides and'the carrier proper willlie below the body of the reference strip and not in such a positionthat it will interfere withthe movement thereof. P

A still further objectfof my invention is the provision of a carrier ofthe type described which shall be provided with a novel frame upon whichthe holders of the reference strips are mounted.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawings: V Fig. 1 is a front elevation ofan indexor directory embodying my improvements showing the carriers hingedto.swing in the manner of leaves; I

Fig. 2is a top plan view of the device shown in Fig. 1;

Fig. 3 is a side elevation of one of the carriers or leaves mounted uponits support;

Fig. 4 is a sectional View on line 44 of Fig. 3; I Fig. 5 is a sectionalview on line 55 of Fig. 3; I

Fig; 6 is a view similar to Fig. 8, but showing a modified form ofcarrier or leaf;

Fig. 7 is a sectional view on line 7-7 of Fig. 6;,and V Fig. 8 is asectional view similar to that shown in Fig. 7, but showing a stillfurther modification of my invention.

To illustrate the principles of my invention,.I have shown an index ordirectory in which the carriers are mounted as swinging leaves similarto those shown inthe patent to R. D. Hayes, above referred to. It willbe understood that my improvements may also be applied to carriers whichare sup ported or suspended in other ways.

In the form of my invention shown in Figs-1 to 5, I'haveshownatlOasuitable support provided with guides 11 at the top andbottom thereof, respectively, in which the carriers or leaves 12 areslidably and swingably mounted The leaves-may, when mounted'in'thismanner, be swung'op'en-in any desired point, as shown, and'when theyareextended as arms to mount the carrier in the guides 11. At the ends ofthese armsare mounted spherical projections 16 to engage in the channelsformed in the guides...

The material of which these arms are made is suiliciently resilient so,that they may be sprung into place and also may be removed at will. Theportion 13 of the frame is shaped to form the rear side edge thereof andalso to overlap the member. Mat the-top and bottom of. the leaf and:theends of'the member 1?; may be soldered at the pointsl? and 18 to therod 1a to secure theparts of the frame rigidly together...

While the details of the structure of the carrier or leaf may bevariedto: some extent, I have. chosen to mount av baseplate or base strip 19upon theframe formed by the rods 13 and 14. This plate may be a thinflat piece of metal andv have its: ends turned overv the rods formingthe frame at the four sides thereof, as shown at 20. Upon the carrierformed by the frameand the base strip just described are provided aplurality of channel guides to retain the strips or cards designed tobear the reference material. These retaining channelsnre formed in theembodiment of my invention which is now being described bythe provisionof a card-holder 21 having aflat base portionsecured flatwise-upon thebase plate 19 and having its sideedges turned. over above the marginalportions of the base plate at 22 and 23 to-provide the retainingflanges. As shown, the holders 21 are thus formed of'one piece ofmaterial and aresecured to the base' plates by rivets; 24 which liebeneath the strips bearing the reference material. Such a strip is shownat 25: in Fig. 3' operatively mounted in the holder and suitably guidedin its movements by the flanges 22 and 23;

When the flanges are turned up at the.

edges of the holder in thisway, it is apparent that any sharp angles orcorners are obviated, as it may be; given arounded shape and thus theedge of" the reference strip is not likely to stick or bind when thestrip is moved. Moreover-,there is no joint between the flange and thebaseplatewherein the referencestrip may become wedged.

The lower edges oftheholders 21 may be turned over at 26 to provide alower retainingflange or support to prevent-the reference strips fromfalling from the holders. Asshownin Fig 3, a plurality of theseholders21 may be mounted upon each-side of the carrier or'lea f,those-on one side thereof beingdirectly opposite the correspondingholderson: the opposite side so that the rivets 2d of 131 16 cairl iertoseeure" theirr totes-1am:

the carrier to its support is employed.

In Figs. 6 and/7, I. have shown a somewhatmodified form ofv my inventionwherein the frame of the carrier is formed in a different way and anovel means of hinging this form the frame is composed of a single redor wire 30, which, as shown, is shaped to formthe rear edge and theupper and lower sides of the frame, the rod being returned upon itselfat the upper and lower edges and extended to form the spring arms 81,which are provided with the hooks 32 adapted to engage the supports 83in a suitable-manner, so that the leaves will be hingedly connected tothese supports. The base plate 19 mounted upon this frame is similar inall respeetsto that described in connection with Figs. 1 to 5, exceptthat the front por-- tion of the same is flanged or hemmed at 3a toprovide additional strength at this edge in view of the fact that theedge is not protected by a part of the rod 30. The holders 21 In Fig. 81have shown a modified form of my invention wherein the retaining flangesare formed by securing relatively narrow strips upon the base plate 19instead of holders 21 which extend throughout the width oftlie referencestrips25. These retaining strips 35 are brought over and secured to thebase plate by the rivets 36 at a point which will lie below thereference strips 25, so that even in this form there will be nov jointin position to obstruct the edges of the strips.- The flanges are thenformed by the edges of the members 35 being turned over in a mannersimilar to the edges of the holders 21. In case of the intermediateflanges formed upon the plate 19, these, if desired, may be formed by astrip of material 37 riveted tothebase plate at 38," carried out ineither direction from the rivet 38- to extendbeneaththe reference strips25, then returned over itselfto-a point adjacent the rivets 38- wherethe edges are flanged at 39 in the usual manner. It will be apparentthat considerable saving of material is achieved in this form, asthematerial formin;- the flanges is not: continued entirely across thebase strip as in the forms of my invention shown in the other figures ofthe drawing. The advantages, however, of the forms of the other figuresin that a rounded flange isprovided and one wherein there is ti'on, isunderstood that'the Same is not to'be' limited t eretoin allot-itsdetails,

but is capable er many' modifleations and variations which lie withinthe spirit of the invention and within the scope of the appended claims.

What I claim is: v 1. In an index or file, a leaf having a surroundingframework ofrods, a base plate bent over and secured to said frameworkand substantially filling the space therein,

and an opposed channelled card holder secured to each face of the leaf,said card holder comprising a continuous flat strip of material with itslateral edges bent back over the body portion to form opposed cardretaining channels.

ing a base plate and a plurality of carrier strips mounted thereon, eachof said carrierstrips having a body portion secured fiatwise upon thebase strip and having edge portions returned over the body portion toprovide opposed retaining flanges, said carrier strips beingmounted'directly opposite each other, back to back, on opposite sides ofthe carrier leaf and securing means passing through the leaf and thestrips on both sides thereof. p

3. In an index or file, a carrier leaf comprising a frame of rods orwire and a base plate mounted therein, said frame being composed of tworods, each bent to form three sides of the frame and overlapping theother rod upon two sides thereof.

4. In an index or file, a carrier leaf frame having spring arms by whichit is supported, sald arms being continued to form the top, bottom andone side of the frame, and a rod secured to said arms and forming theother side of the frame.

5. In an index or file,a carrier frame of substantially rectangularshape and formed of two rods, the ends of one rod being secured tointermediate portions of theother,

andthe ends of the second rod being ex-- tended to be secured to asupport.

6. In an index or file, a carrier or leaf body portion to. provideretaining flanges and also having an end edge turned up to provide asupporting flange.

7. A leaf index for holding cards or the like, comprising a base plate,a supporting framework surrounding and secured to said base plate, and aseamless one piece card 2. In an index or file, a carrler leaf hav-'holder attached to said base plate, said card holder having single bendsupon its lateral edges whereby a portion is turned inward from each ofsaid edges toward the median line of said holder to form card retainingflanges.

' 8. In an index or file, a carrier leaf comprising a framework composedof two rods each bent to form three sides of the frame, a base platesecured to the rods connecting the opposite sides of the frame together,and channeled card holding strips upon said base plate. 9. In an indexor file, a carrier leaf comprising a rodbent to form three sides of arectangular frame, a base plate connecting the three sides thus formedtogether, and

reinforcing strips upon said base plate, said reinforcing strlps beingseamless pieces of material applied flatwise to said plate and havingtheir lengthwise edges bent inward to form retaining flanges of singlethickness for cards or the like.

In witness whereof, I have hereunto set
